a mod which sets income to 0 if you have an even number of territories would create exciting new challenges

this could even be implemented as a map landria-esque

oh that sounds interesting, mod is on its way :)

Some test games for the mod:

Trivia: why the mod sucks?

this could even be implemented as a map landria-esque

I forget the name of the map, but it's an INSS map that has red and blue bonuses, where the red gives you negative income if you have an even # of territories within the bonus and regular credit for the bonus if you have an odd #, and blue does the opposite

Not exactly what you said, but it's arguably better - going from full income to 0 is too harsh, but 0 or slightly negative income from a specific bonus is manageable

But it's just 1 map, so no variety, whereas a mod could do this or something similar for every map

Using this mod in addition to an INSS/Landria/other type map would be brutal tho!

territory cap instead of army cap, but how would it decide? lots of different ways this could go, but a very cool idea

Mod is now public :)
